Free courses give you a general experience, and more in-depth content needs to be paid.
In the early stage of the study group, it is true that systematic courses are used to lay the foundation, but not only systematic courses, but also 800 core words, including math summer camp, English life-saving class, writing group, cramming class, punching class, composition class and so on. In addition, the most important thing is that the study group has a study plan every week, the teacher takes you to study systematically and efficiently, and the teaching assistant provides timely answer services in the Q&A group. There is a touch-up exam before entering the school, and a monthly exam is arranged once a month to track the students' learning progress and grasp the situation, and timely check and fill the gaps. Students can spend less time studying and go ashore efficiently. I also sent a full set of books and all the reference materials this year. This is its value.
